DFSMSrmm is an IBM z/OS feature that is a fully functioning tape management system to manage your removable media. In the last decade, many enhancements were made to DFSMSrmm. This IBM Redbooks publication is intended to help you configure and use the newer functions and features that are now available.

Discussion of the new features is included along with use cases. Hints and tips of various common DFSMSrmm problems and useful configuration and reporting JCL also are included.

This publication is intended as a supplement to DFSMSrmm Primer, SG24-5983, which is still the recommended starting point for any users new to DFSMSrmm.
